call doesn't quit correctly on mac

[GoogleCodeExporter]

What steps will reproduce the problem?
1. run call on mac
2. login then quit

What is the expected output? What do you see instead?
On linux, call quits correctly, On mac, "bus error" happens, application 
doesn't return correctly

What version of the product are you using? On what operating system?
The same problems happens with 0.5 and 0.5.1. On mac 10.6.

Please provide any additional information below.
I would assume application doesn't shutdown all threads correctly, call stack 
attached below. I can provide more info if needed.
quit
(call)
logged out...
(call) Cleanup 

(Here, I pressed return key because application doesn't return)

Program received signal SIGUSR1, User defined signal 1.

I think the problem is close(stdin) is not able to force fgets to quit on mac, 
need to find a different way to exit from fgets.

I'm no longer be able to repro this again. What I did was that after type in 
"quit", give it few sec then press "Enter" key. The app will exit normally.
